The seats are wide with leg room, even on a center seat.

Couldn't check in online, or at a kiosk, because my reservation couldn't be found. Of course, I did have one, and it took going to a counter to get it straightened out, but only after a loooong wait and then barely making it to the gate in time for boarding. Before a 90-minute delay.

It's nice to be theoretically in zone 2

Boarding is inconsistant. At JFK it was like boarding a plane in China. Everyone congested at the front. One Delta person taking tickets. Two Delta people not helping her. We boarded slowly, partially because people STILL refuse to check bags that are not carry on bags. We left late. Why have zones at all? Why have carrying rules that you don't enforce? Why did we pay $25 a bag if you don't enforce this? Food choices are funny, especially the "tapas". Whoever thinks THOSE are tapas should Google the word tapas. Delta reportedly earned 746 million in the first quarter and you charge for everything and still can't come up with decent food for us to BUY?

Friendly, capable attendants, smooth & efficient boarding process. A couple decent free snack options. Due to it being an older plane, leg room is decent.

This and it’s return flight (back to back with a red-eye) are on an older plane without charging ports for all the devices we have nowadays. Makes it difficult to get a full charge to last for the 6 hour flight. Could have used another round of beverage offerings as the air is so dry and warm. Other than that nothing really to complain about!

Prices are per person, are for e–tickets and include all taxes & fees in CAD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
